daeth rheoliad sylweddau teneuo'r osôn i rym ym mis hydref 2000
the ozone depleting substances regulation came into effect in october 2000

mae trafodaethau ar droed hefyd ynghylch rheoliadau i gyfyngu allyriadau toddyddion -- un o ragsylweddion osôn

ychydig wythnosau wedyn , nodwyd bod twll osôn y pegwn yn fwy nag erioed yn ôl y cofnodion er gwaethaf protocol montreal

the ozone depleting substances regulation is about refrigerators , as those of us who have sat on the environment , planning and transport committee know only too well
